After the signing of the armistice between the Allies and Germany on November 11, 1918, the creation of the Kingdom of Serbs, Croats, and Slovenes was proclaimed in Belgrade on December 1, incorporating Vojvodina. However, the official end of World War I is considered to be the signing of the Treaty of Versailles on June 28, 1919.
The People's Council of the Kingdom of Serbs, Croats, and Slovenes was responsible for issuing orders for the censorship of postal shipments. The main military censorship for Vojvodina was located at the Main Belgrade Post Office, and starting from April 1, 1919, all main post offices in the rear area came under the administration of the Ministry of Posts. The Novi Bečej post office had two types of censorship stamps, used in January and February 1919. The first, from January, was handmade and featured the Cyrillic inscription: "CENZURA TBEČEJ." The second stamp, also written in Cyrillic, was of very fine craftsmanship and in three lines, stating: "CENZURA | TURSKO BEČEJSKE | SRPSKE VOJNE VLASTI." After the censorship office in Novi Bečej was abolished, all mail was sent for censorship to Novi Sad and then to its destination.
During the final demarcation period (1919–1921), postage stamps with the inscription "Država SHS" (State of SHS) were used. The postal cancel TÖRÖK BECSE and ARACS continued to be used for canceling stamps of the newly formed State of SHS until December 1921, despite the decision of the Turkish Bečej Council in May 1920 to change the name from Turski Bečej to Novi Bečej, as published in the "Srpski glas" newspaper in Kikinda.
